DF32 Discless Logic Test

This document describes the 'Discless' diagnostic program (MAINDEC-8/1-D58B-D) designed for the PDP-8/I computer. The program tests the DF32 disc logic and the interface to the computer without requiring the disc itself. It includes requirements for equipment (PDP-8/I with DF32 logic, optional light card), loading and starting procedures, and detailed error codes with corresponding corrective actions. The manual also provides a program discussion, flow charts for tests, and a complete source code listing.
